摘要
为了准确检测和分析电网谐波研制了一种便携式钳形电流谐波分析仪,它是基于数字信号处理DSP(DigitalSignalProcessing)技术和现代检测技术,实现了实时测量分析和历史数据管理等功能,具有操作简单、小巧轻便等优点,可以取代普通的钳形电流表。该设备达到了国家标准对谐波测量、分析的要求。
A portable clamp current harmonic analyzer is developed for real-time and correct analyzing power network harmonic,which is based on DSP(Digital Signal Processing) and modern detection techniques. It realizes the real-time measuring and analysis and the historic data mana-gement. It is small and light,easy to operate,which can replace the normal clamp current meter. It meets the requirements of national standards for harmonic measuring and analysis. This project is supported by the Key Scientific Fund of Guangdong Province(A1050202).
